Just wondering if two ground plane radials are attached to the antenna mounting point parallel to the jeep's rear panel,would that provide an adequate ground plane. The antenna mounting point would have to be well grounded to the back of the jeep or else the coax is the ground plane.
Oh boy, let me try my best here.
From what I understand the coax is the ground plane. The underside of the mounting surface is sanded to the bare metal as what was described in the instructions. I see many people with fine results using this mount, but I never once got lucky with it.
Do you think the walls of the hole itself need to be sanded? I am pretty darn sure I did that too. The stud looks to be in good shape, and I used a new coax. I have another SWR meter arriving this week, in addition to the one I already have, to negate any uncertainty I may be using a faulty meter.
Since I am more into DX etc. I assume I will be very happy with my Sirio, regardless.
